- skidding Devices; and lowing to be a full, clear, j tion of the invention, others skilled in the art I "being Be it known that I, WILLIAM S. Charm-a citizen of the United States, residingat'St.

of Ohio, have invented certain new and 'us- 'ful Improvements in and exact descrip- -such as will enable tains to make and use thesame,

had to the accompanying drawings, and to the letters and figures ofrefe'rence marked thereon, which form a part ofthi's specification.

This invention relates to new and useful improvements in anti-skidding devices for automobile wheels. 3

The object of the invention is to provide a device of this type that may be attached to an automobile wheel, and which will,

when placed inan operative position, prevent the wheels slipping on 'ice and snow, or sidewise, when the'machine is goin around a curve, as hereinafter set forth scription and drawings, the claims.

Referring to the drawings, Figure 1 is a side elevation of an automobile wheel equipped with the invention; Fig. 2 is a section onthe line a--a of Fig. 1; Fig. 3 1s a longitudinal section of an automobile chassis,

. showing the operating or setting mechanism;

Fig. 4 is a top plan view-of the same;.Fig. 5 is a section on the-line b-b of Fig. 1; Fig. 6 is a section on the line 0--c'of Fig. 2; and Fig. 7 is a detail view of the trip device.

Referring more particularly to the drawings, 1 represents the frame of an automobile provided with a rear axle 2, on the outer ends of which are mounted theusual automobile wheels. consistsof a hub 3, spokes 4, felly 5, rim 6 and tire 7. The wheels as above described, are well known partsof an automobile,

' during the operation of the automobile, said wheels are subject to slipping 'on ice and snow and to skidding when making a curve. To obviate these objections, the following attachmentjs provided. Mounted on the rim 6 is a plurality of bearings 8, and passing through each of these hearings is a pintle'9 on the outer end of which is mounted a'hub 10 providedwith a spur 11.. The spur 11 is, therefore pivotallymounted on the pintle in the county of Auglaize and-State Creeping and "Anti- I do declare the :fol-l;

to which it apperreference in theide; and pointed out in Each of these wheels and ,an operative relation with" the ground. In Fig.1}; the spurs are shown in an operative position in full lines, and, the upper spur is shown; in an inoperative position in dotted lines. The spurs 11 are thrown in and out, of position-as follows: All of the spurs 11 are connected by means of links 12, to a ring '13 mounted'in bearings 14" attached to the, spokes 4. It willbe seenthat, when the ring 13 is'shifted in one direction, the spurs 11 will'be thrown to anoperative'position, and when the ring is shifted in the opposite direction, the spurs will be thrown to an inoperative POSlt-lOH. 'The ring is shifted as follows: Mounted on said ring 13 is a pin 15. adapted to be .enga ed by a trip 16, as is shown in Figs. 3 an pivotally mounted on an arm 17, and is held in agc'entral-position by means of a spring 18. The spring 18 allows the pin 15 to pass the trip'16, but is of sufiicient tension to shift the ring 13. There is a trip 16 and an arm 17 for each rear wheel, and the arms 17 are mounted ona rock shaft. 18* journaled in the frame. -The shaft 18? is provided with an arm 19 connected to a hand lever 20 by a rod 21. It will be seen that, when the trip 16 is placed in operative relation with the pin 15, the ring 13 and the spurs 11 will be shifted from one position to the other. The arrangement is such that when the machine is going forward and the trip is placed in a position to engage the pin 15, the spurs will be thrown from an inoperative to an operative position; and when the direction of the machine is reversed, the spurs will be thrown to an inoperative position. I When the spurs 11 are in an operative position and are engaging the ground, the strain incidental engaging lugs 23-on the bearings 8, thereby limiting the movement of the spurs. The spurs 11. are held in either of their positions by means of leaf springs 24 which engage hexagonal portions 25 of the hubs 10. These springs 24 prevent the spurs 11 being shifted by the jarring of the machine; and being of a resilient nature, permit the spurs to be shifted positively bythe trip 16. Y

To prevent the spurs being injured when striking a stone or the like, said spurs are capable of a slight lateral movementwhich is accomplished as follows. The hubs 10 are provided with ball portions 26' which fit-in 4. The trip 16 is sockets 27 in the bearings Saidhubs 10 are capable of a longitudinal movement on laterally and pass to the side of an obstrucspurs in a normal tion, while the springs 28 tend to hold the position.

I claim:

1. In a device of the type specified, the

combination with a wheel, of a series of bearings comprising socket members mounted thereon, a corresponding series of bearings comprising hubs with ball portions engaging said socket members, a spur rigidly united to each of said hubs, a pintle projected through axial openings in the socket and hub members and whcreon said hub has a rocking and longitudinal movement which enables the spur to have the necessary movement, and means for'rocking all of the spurs o the simultaneously through'the movement hub members of the bearings, substantially as specified.

2. automobile wheel having the usual rim supporting a rubber tire, an oscillating ring mounted in bearings on the spokes of said wheel adjacent to said rim, a pin projecting laterally from said ring, socket bearings 'extending laterally from said rim, a series of spurs having heads provided with ball portions adapted to enter said sockets, said spurs being adapted to be projected beyond the circumference of the tire, a series of links connecting said spurs and said ring, headed pins penetrating the heads of the 'spurs and their socket bearings, a resilient member mounted between each of the spurs and pin heads, thereby allowing the spurs to have a flexible lateral movement, a second resilient member engaging each spur head and adapted to hold the s urs in a set position, and means for shi ting said ring torock said spurs in a body to and from operative positlons. I

In testimony whereof I aflix my signature, in presence of two witnesses.
